or pharmaceutically acceptable salts thereof, in which R₁, R₂, R₃ and R₄ are defined as described below.

The present invention also relates to a process for preparation of the compound of formula (I) and to an anticancer composition comprising the compound of formula (I) as an active ingredient.

BACKGROUND ART

Mammalian Ras proteins act as molecular switches in the signalling events associated with cell growth and differentiation. The ras proto-oncogene family consists of three members, N-, K-, and H-ras, which code for highly homologous four types of proteins; i.e. H-, N-ras proteins of 189 residues and two isomorphic K-ras-4B and K-ras-4A proteins of 188 and 189 residues, respectively. The chemical basis for the switch mechanism involves cycling of the protein between the inactive (off) guanosine diphosphate (GDP) bound state and the active (on) guanosine triphosphate (GTP) bound state (Bourne. H. R.; Sanders, D. A.; McCormick, F.; Nature, 1991, 349,117). Biochemical and structural studies have shown that point mutations of the residues 12, 13, and 61, positioned in the neighborhood of phosphoryl group of GTP, resulting in the decrease of guanosine triphosphatase activity are associated with many human cancers, particularly, pancreatic cancer, urinary bladder carcinoma, colon cancer, etc. (Bos, J. L., Cancel Res., 1989, 49, 4682).

Ras protein is synthesized as a cytosolic precursor that is ultimately localized to the cytoplasmic face of the plasma membrane after a series of posttranslational modification (Gibbs, J. B., Cell 1991, 65, 1). These series of biochemical modifications, by changing the electrical charge state or spacial structure to increase the hydrophobicity allow Ras protein to attach to cell membrane more easily. The first and obligatory step in the series is the addition of a farnesyl moiety to the cysteine residue of the C-terminal CAAX motif (C, cysteine, A, usually aliphatic residue; X, any other amino acid) in a reaction catalyzed by farnesyl protein transferase (FTase). This modifications is essential for Ras function, as demonstrated by the inability of Ras mutants lacking the C-terminal cysteine to be farnesylated, to localize to the plasma, and to transform mammalian cells in culture (Hancock, J. F., Magee, A. I., Child, J. E., Marshall, C. J., Cell 1989, 57, 1167). The subsequent posttranslational modifications, cleavage of the AAX residues, carboxyl methylation of the farnesylated cysteine, and palmitoylation of the cysteines located upstream of the CAAX motif in H-and N-ras proteins are not obligatory for Ras membrane association or cellular transforming activity. Interestingly, K-ras-4B, different from H- and N-ras, has a multiple lysine rich region named polybasic domain, instead of having cysteine required for palmitoylation, thereby facilitating the farnesylated ras protein to bind to anionic lipid layer of cell membrane. The inhibitors of FTase that catalyzes the obligatory modification have therefore been suggested as anticancer agents for tumors in which Ras oncogene contributes to transformation (Buses, J. E. et al., Chemistry & Biology, 1995, 2 787). A number of FTase inhibitors have recently identified demonstrated potent and specific ability to block Ras farnesylation. signalling and transformation in transformed cells and tumor cell lines both in vitro and in animal models (Koh, N. E. et al., Proc. Natl. Acad. Sci. USA, 1994, 91, 914; Kohl, N. E. et al., Nature Medicine. 1995, 1 792). However, most of the inhibitors are related to CAAX motif as Ras substrate mimic and peptidie in nature or contain a sulfhydryl group (U.S. Pat. No. 5.141,851; Kohl, N. E. et al., Science, 1993, 260, 1934; PCT/US95/12224, Graham et al., Sebti, S. M. et al., J. Biol. Chem., 1995, 270, 26802; James, G. L. et al., Science, 1993 260, 1937; Bishop, W. R. et al., J. Biol. Chem., 1995, 270, 3061 1) Recently, a new type of peptidomimetic inhibitor imitating catalytic step of FTase has been reported (Poulter, C. D. et al., J. Am. Chem. Soc., 1996, 118,8761). The chemical basis of the inhibitor design relates to the reaction mechanism. That is, transferring prenyl group by the enzyme is electrophilic displacement and the reaction requires (+) charge in a transition state.

These inhibitors previously described however possess limited activity and selectivity for inhibition of the oncogenic function of Ras proteins, particularly K-ras-4B, which is found to be most common in human cancer. Therefore, new inhibitor having the ability of effectively inhibiting K-ras activity is required.

Experimental Example 1 Analysis of Ras Farnesyl Transferase Inhibiting Activity

In the present experiment, Ras farnesyl transferase produced by genetic recombination techniques by the improved Pompliano's method(Pompliano et al.; Biochemistry, 1992, 31, 3800) was used, Ras substrate (Ras-CVLS) protein was used by purifying by the known method(Chung et al., Biochemicia et Biophysica Act. 1992, 278, 1129).

The enzyme reaction was performed in 50 μl of 50 mM Sodium HEPES buffer solution containing 25 mmol of potassium chloride. 25 mmol of magnesium chloride, 10 mmol of DTT and 50 μmol of zinc chloride. 1.5 μmol of Ras substrate protein, 0.15 μmol of tritium-farnesylpyrophosphate and 4.5 nmol of farnesyl transferase were used.

More specifically, in the initial step, farnesyl transferase was added to the above buffer solution, reaction was maintained for 30 minutes at 37° C. and then the reaction was stopped by adding 1 ml of ethanol solution containing 1M HCl. The formed precipitates were adsorbed to GF/B filter using Hopper harvestor(Hopper #225V) for filter-binding, washed with ethanol, and then radioactivity of the dried filter was measured using LKB β counter. Enzyme titer was measured in the unsaturated state of substrate where the concentrations of Ras substrate protein and farnesyl transferase have quantitative relationship. Enzyme inhibiting activity was measured using less than 5% of total reaction solution of the compound according to the present invention dissolved in dimethylsulfoxide(DMSO) solution as a reagent. Enzyme inhibiting activity was represented by percentage of the amount of the farnesyl incorporated with the reagent to that without the reagent. IC₅₀ of the reagent was defined as the concentration inhibiting the enzyme activity by 50%.

To evaluate the selective enzyme inhibiting activity of the compound according to the present invention, inhibiting activity on geranylgeranyl transferase was measured. Geranylgeranyl transferase was purified from bovine brain with the method modified from Schber's method(Schber et al., J. Biol. Chem. 1990, 265, 14701). and substantially the same experiment as that of farnesyl transferase was performed using geranylgeranyl pyrophosphate and Ras-CVIL substrate protein under the similar condition to farnesyl transferase reaction.

In the present experiment, Rat2 cell line which expresses C-Harvey-Ras protein having transforming activity and Rat2 cell line(Korean patent application No. 97-14409) which is transformed with fused protein of H-Ras substituted with polybasic lysine domain at C-terminus of K-Ras were used. The experiment was performed by the modified Declue's method(Declue. J. E. et al., Cancer Research, 1991. 51, 712). Hereinafter, the experimental method will be described in more detail.

3×10⁵ cells of transformed Rat2 fibroblast cell line were sprayed on 60 mm cell cultivation dish and cultivated for 48 hours in a cell incubator at 37° C. and after 50% or more of density was reached, it was treated with a reagent. The compound according to the present invention dissolved in dimethylsulfoxide(DMSO) was used as the reagent. 1% of dimethylsulfoxide was used in both control and experimental groups. After 4 hours from the treatment of the reagent, methionine labeled with 150 μCi of radioactive isotope, ³⁵S per 1 ml of medium, was added and after cultivating for 20 hours, the cells were washed with physiological saline water. The cells were lysed using 1 ml of cool cell lysis buffer solution(50 mM of Sodium Herpiss buffer solution containing 5 mmol of magnesium chloride. 1 mmol of DTT, 1% NP 40, 1 mmol of EDTA, 1 mmol of PMSF, 2 μmol of leupeptin, 2 μmol of pepstatin A and 2 μmol of antipain) and the supernatant was obtained by high-velocity centrifugation of 12,000 g×5 minutes. The amount of the labeled radioisotope of the supernatent was measured and standardized to obtain a quantitative result in immunoprecipitation reaction and then. Y13-259, monoclonal antiboby specifically binding to Ras protein(Furth, M. E. et al., J. Virol, 1982, 43, 294) was added and reacted for 15 hours at 4° C. Protein A bound to goat anti-murine Immunoglobulin antibody-agarose suspension was added to the solution and reacted for 1 hour at 4° C. and then, to remove unspecific binding product, immunoprecipitates were washed with buffer solution(50 mM Tris chloride buffer solution containing 50 mmol of sodium chloride, 0.5% of sodium dioxycolate, 0.5% of NP 40 and 0.1% of SDS). The precipitates were boiled in reagent buffer solution for electrophoresis and then, electrophoresis was performed using 13.5% of SDS polyacrylamide gel. After electrophoresis, the gel was fixed and dried. Then, the gel was exposed to X-ray film, developed and printed. From the result of the experiment, intensities of band of protein with and without farnesyl of Ras protein were measured, and the concentration of reagent inhibiting 50% of farnesyl binding was defined as CIC₅₀, an intracellular Ras farnesyl transferase inhibiting activity.
